The World Wide Web is emerging not only as an infrastructure
for data, but also for a broader variety of resources that are
increasingly being made available as Web services. Relevant
current standards like UDDI, WSDL, and SOAP are in their
fledgling years and form the basis of making Web services a
workable and broadly adopted technology. However, realizing the
fuller scope of the promise of Web services and associated service
oriented architecture will requite further technological advances
in the areas of service interoperation, service discovery, service
composition, and process orchestration. Semantics, especially as
supported by the use of ontologies, and related Semantic Web
technologies, are likely to provide better qualitative and scalable
solutions to these requirements. Just as semantic annotation of
data in the Semantic Web is the first critical step to better search,
integration and analytics over heterogeneous data, semantic
annotation of Web services is an equally critical first step to
achieving the above promise. Our approach is to work with
existing Web services technologies and combine them with ideas
from the Semantic Web to create a better framework for Web
service discovery and composition. In this paper we
present MWSAF (METEOR-S Web Service Annotation
Framework), a framework for semi-automatically marking up
Web service descriptions with ontologies. We have developed
algorithms to match and annotate WSDL files with relevant
ontologies. We use domain ontologies to categorize Web services
into domains. An empirical study of our approach is presented to
help evaluate its performance.
